随着我国社会主义建设事业的蓬勃发展,迫切要求建筑材料向轻质量、高强度、大型化、预制化方向发展。在批林批孔运动推动下,在市局各级领导的关怀和支持下,我们四个单位组成了三结合研制小组,研究试制轻质混凝土墙板。基本完成了用膨胀珍珠岩砂与粉煤灰陶粒作集料配制轻质混凝土的材性研究,初步进行了墙板的试制和检验工作。一、轻集料混凝土原材料与配合比 1.原材料胶结材料:天津水泥厂生产的400号矿
With the vigorous development of China’s socialist construction, it is urgent for building materials to develop in the direction of light weight, high strength, large scale, and prefabrication. Under the encouragement of the approval of the Lin Piao and Confucius Movement, under the care and support of leaders at all levels of the City Council, we formed a three-combination research team to study the trial production of lightweight concrete wall panels. The study of the properties of lightweight concrete with aggregates of expanded perlite and fly ash as aggregate was basically completed, and preliminary trials and inspections of wallboards were conducted.
